SPECIFICATION forming part of Letters Patent No. 471,180, dated March 22, 1892.

Application filed May 28, 189].. Serial No. 394,345. (No model.)

To aZZ whom it may concern,.-

Beit known that I, HENRY ERASTUS KINGS- LEY, of Sweet Home, Pulaski county, Arkansas, have madea new and useful Improvement in Shingle-Edginglllachines, of which the following is a full, clear, and exact description.

The present improved machine is designed for edging dimension shingles. A revolving` polyhedral drum is employed, in combination with a system of saws, the shingles being applied to the drum-faces as they, in the rotation of the drum, come successively into position to receive the shingles and the shingles being carried by the drum past the saws and thereby edged and then discharged from the drum, substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which- Figure 1 is a side elevation of the improved machine; Fig. 2, a plan of the same; and Figs. 3 and 4t details, Fig. 3 being a vertical longitudinal section through the drum in the plane of one of the saws, and Fig. 4 a similar section in the plane of one of the shingle-dischargers.

The same letters of reference denote the same parts.

A represents the drum, whose faces a a a constitute an endless series of bed-plates for supporting the shingles in theirV passage through the machine. The drum is attachedV to the shaft B, which is journaled in suitable bearings b, supported in or upon the frame C of the machine. Said frame consists, preferably, of the uprights o c at the sides, respectively, of the machine and the horizontal portion c2, which connects with the uprights at a suitable level for supporting said shaftbear ings. Said drum may be of any suitable diameter and width, and it may have any desirable number of faces a so long as said faces in height and width are adapted to support and carry the work which is being operated upon. In the present instance the drum has eight faces a.

D D l)2 D3 represent a system of circular grooved or divided, substantially as is repre-1 v sented at a a2 a3 a4, to receive the peripheral .preferably in the form of the pins al, are also provided at or near the sides, respectively, of the drum-faces for supporting the Work at- `the side edge or edges thereof while upon the drum.

An additional feature of the construction is what might be termed the dischargers E E E2 E3 E4. Their function is to lift the points of the shingles after they have been edged, so as to separate the shingles from the drum-face and cause them to be discharged from the drum and machine into any suitable receptacle. (Not shown.) To this end and as the most desirable construction therefor the dischargers consist of iat strips of spring-steel fastened at one end e to some xed part c3 of the frame O and extending thence to enable their free ends e to come beneath the points of the shingles as they are carried around upon the drum to the point at which it is desired to discharge the shingles and cause them to be slipped from the drumface onto said strips. Each drum-face, by means of the described grooves or divisions a a2, the., is subdivided into the parts as a9 am a cl2, and. said dischargers are arranged, respectively, in line with said subdivisions of the drum-face, and to enable the end e of the discharger to readily come beneath the shingle upon the drum-face division to which that discharger belongs said division is notched or slotted, substantially as shown at als, to receive said end e', substantially as shown.

In operating the machine the shingle or shingles to be edged are placed upon a face of the drum withthe lower end orbutt thereof against the pins a and with the side or sides roo against the pins cti-that is, a single shingle upon the drum-face maybe supported at one side edge only, and if two shingles are placed side by side upon the drum-face they maybe respectively supported laterally by the pins a7 at the sides, respectively, of the drum. Motion being imparted to the saw-arbor-say by means of a belt leading to the pulley cl3, attached to said arbor-the saws are rotated in the direction indicated by the arrow CZ", and the drum is rotated in the direction indicated by the arrow x. Any suitable means may be adopted for imparting said motion to the drum, and the drum motion may be derived from the saw-arbor motion, and in such case any suitable means may be employed to suitably transmit the motion. A desirable means is indicated in the drawings.

F represents a friction-wheel journaled at fin an arm Gr. Said arm is journaled upon a shaft 7L, and it is extended at g to sustain a weight g', and thereby cause the periphery of the wheel F to bear against the arbor d. The shaft of said wheel F is provided with a pinion F', which engages with a gear l-I upon the shaft h. Said last-named shaft is also provided with a pinion ll', which engages with the gear I upon the shaft t'. Said lastfnarned shaft is provided with a pulley I', from which a belt J leads to a pulley K upon the drumshaft B. The motion of the saw-arbor by this means and as indicated by the arrows x x2 x3 is communicated to said shaft B and the drum is rotated in th'e described direction. The shingles are carried in the rotation of the drum past the saws, and are thereby properly edged, and the edged shingles are ultimately delivered onto the strips E E', the., and thence from the machine, and the waste incident to the described edging is dropped through the space L between the drum and the part c3 of the frame C. The drum motion is necessarily much slower than the saw-arbor motion, and the operative is enabled to apply the shingles to the drum-faces as they successively in the rotation of the drum come into position in front of the saws to receive the shingles.

The drum can be constructed in any suitable manner to enable the divisions d d2, duc., to be formed, and the saws may be secured to the arbor in any suitable manner, substan tially as described.

I claiml. The combination of the drum and the system of saws, said drum having faces d and grooved and divided to receive the peripheral portion of the saws and the shoulder d a and slotted at am am, with the Adischargers E E', the., substantially as described.

2 The combination of the system of saws and the revolving drum having the faces aand slotted, as described, with the dischargers E E', dac., substantially as described.

3. The combination of the revolving drum having` the faces CL and the shoulders a a7 and slotted at am als, a system of saws, and the dischargers, substantially as described.

Vitness my hand this 19th day of May, 1801.
